Array-based multiplex analysis of candidate genes reveals two independent and additive genetic risk factors for myocardial infarction in the Finnish population.
We analysed common variants of eight genes implicated previously as risk factors for coronary heart disease or myocardial infarction (MI) in a cross-sectional study on patients with a history of MI and in carefully matched controls from the Finnish population. The most common low density lipoprotein receptor mutations in Finland were also included in our analysis. Multiplex genotyping of the target genes was performed using a specific and efficient array-based minisequencing system. The 4G allele of the plasminogen activator inhibitor gene (P
